WORKING PRINCIPLE
A
NEW EXCALIBUR
The NEW J11
EXCALIBUR unit is defined “electric piston pump”.
An electric piston pump is used for high pressure painting without
air (from this process derives the term ”airless”).
The pump is controlled by an electric motor coupled with a
reduction gear.
A cam shaft and a connecting rod allow to obtain the reciprocating
motion necessary to the working of the “pumping group” piston.
The piston movement produces a “vacuum”.
The product is sucked, pushed towards the pump outlet and
then sent to the gun through the flexible hose.
A electronical device on the side of the reduction gear casing,
allows to adjust and control the pressure of the material coming
out of the pump.
When the pump reaches the set value, the motor stops and
starts again when the value decreases.
A safety valve avoiding overpressure, guarantees the total
reliability of the equipment.
“Top Finish” version.
“Top Finish” version allows to choose between Airless and
Mistless painting.
The machine works with basic system Mistless and to choose
the airless system it is necessary to close the air supply and
replace the type of spraying gun.

E
• THE EMPLOYER SHALL TRAIN ITS EMPLOYEES ABOUT
ALL THOSE RISKS STEMMING FROM ACCIDENTS, ABOUT
THE USE OF SAFETY DEVICES FOR THEIR OWN SAFETY AND ABOUT THE GENERAL RULES FOR ACCIDENT
PREVENTION IN COMPLIANCE WITH INTERNATIONAL
REGULATIONS AND WITH THE LAWS OF THE COUNTRY
WHERE THE PLANT IS USED.
.
.
The user is responsible for the operations of unloading and handling and should use the maximum
care so as not to damage the individual parts or
injure anyone.
To perform the unloading operation, use only qualified
and trained personnel (truck and crane operators, etc.)
and also suitable hoisting equipment for the weight
of the installation or its parts.
Follow carefully all the safety rules.
The personnel must be equipped with the necessary
safety clothing.
.
.
.
The disposal of packaging materials is a customer’s
competence and must be performed in accordance
with the regulations in force in the country where the

instructions in a safe place.
The unauthorised tampering/replacement of one
or more parts composing the machine, the use of
accessories, tools, expendable materials other than
those recommended by the manufacturer can be
a danger of accident.
The manufacturer will be relieved from tort and
criminal liability.
• KEEP YOUR WORK PLACE CLEAN AND TIDY. DISORDER
WHERE YOU ARE WORKING CREATES A POTENTIAL RISK
OF ACCIDENTS.
• ALWAYS KEEP PROPER BALANCE AVOIDING UNUSUAL
STANCE.
• BEFORE USING THE TOOL, ENSURE THERE ARE NOT
DAMAGED PARTS AND THE MACHINE CAN WORK PROPERLY.
• ALWAYS FOLLOW THE INSTRUCTIONS ABOUT SAFETY
AND THE REGULATIONS IN FORCE.
• KEEP THOSE WHO ARE NOT RESPONSIBLE FOR THE
EQUIPMENT OUT OF THE WORK AREA.
• NEVER EXCEED THE MAXIMUM WORKING PRESSURE
INDICATED.
• NEVER POINT THE SPRAY GUN AT YOURSELVES OR
AT OTHER PEOPLE. THE CONTACT WITH THE CASTING
CAN CAUSE SERIOUS INJURIES. IN CASE OF INJURIES
CAUSED BY THE GUN CASTING, SEEK IMMEDIATE MEDICAL ADVICE SPECIFYING THE TYPE OF THE PRODUCT
INJECTED. NEVER UNDERVALUE A WOUND CAUSED BY
THE INJECTION OF A FLUID.
• ALWAYS DISCONNECT THE SUPPLY AND RELEASE
THE PRESSURE IN THE CIRCUIT BEFORE PERFORMING ANY CHECK OR PART REPLACEMENT OF THE
EQUIPMENT.

• TIGHTEN AND CHECK ALL THE FITTINGS FOR CONNECTION BETWEEN PUMP, FLEXIBLE HOSE AND SPRAY GUN
BEFORE USING THE EQUIPMENT.
• ALWAYS USE THE FLEXIBLE HOSE SUPPLIED WITH STANDARD KIT. THE USE OF ANY ACCESSORIES OR TOOLING
OTHER THAN THOSE RECOMMENDED IN THIS MANUAL,
MAY CAUSE DAMAGE OR INJURE THE OPERATOR.
• THE FLUID CONTAINED IN THE FLEXIBLE HOSE CAN
BE VERY DANGEROUS. HANDLE THE FLEXIBLE HOSE
CAREFULLY. DO NOT PULL THE FLEXIBLE HOSE TO
MOVE THE EQUIPMENT. NEVER USE A DAMAGED OR A
REPAIRED FLEXIBLE HOSE.
The high speed of travel of the product in the hose
can create static electricity through discharges
and sparks.
It is suggested to earth the equipment.
The pump is earthed through the earth cable of
the supply.
The gun is earthed through the high pressure
flexible hose.
All the conductors near the work area must be
earthed.
Electrical safety precautions
• Check the switch is on the "OFF" position before connecting
the cable to the mains
• Never carry a plugged-in equipment.
• Disconnect the equipment before storing it and before
performing any maintenance operation or replacing of
accessories.
• Do not carry the equipment neither unplug it by pulling the
electric cable.
• Protect the cable from heat, oil and sharp edges.
• When the tool is used outdoors, use only an extension
cable suited for outdoor use and so marked.
Never attempt to tamper with the calibre of instruments.
.
• NEVER SPRAY OVER FLAMMABLE PRODUCTS OR SOLVENTS IN CLOSED PLACES.
• NEVER USE THE TOOLING IN PRESENCE OF POTENTIALLY
EXPLOSIVE GAS.
Always check the product is compatible with the
materials composing the equipment (pump, spray
gun, flexible hose and accessories) with which it
can come into contact. Never use paints or solvents containing halogen hydrocarbons (as the
methylene chloride).
If these products come into contact with aluminium
parts can provoke dangerous chemical reactions
with risk of corrosion and explosion.
IF THE PRODUCT TO BE USED IS TOXIC, AVOID
INHALATION AND CONTACT BY USING PROTECTION GLOVES, GOGGLES AND PROPER
FACE SHIELDS.
TAKE PROPER SAFETY MEASURES FOR THE
PROTECTION OF HEARING IN CASE OF WORK
NEAR THE PLANT.
• Take care when the pumping rod is moving.
Stop the machine whenever someone is within its vicinity.
• Repairs of the electrical equipment should only be carried
out by skilled personnel, otherwise considerabledanger to
the user may result.
